$PECIPICATION forming part of Letters Patent No. 380,500, dated April 3, 1888.

Application riled September 12, 1887. Serial No. 249.469. (No model.)

To all whom it may concern.-

Beit known that I, Joan F. Lnvsoor'r, a citizen of the United States, residing at Jefierson, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cook-Stove Ventilators, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain novel improvemeutsin ventilatinghoods, which are designed for carrying off from cook-stoves the odors, steam, and undue heat generated while cooking; and the nature of my invention consists in a ventilator or stove attachment made in sections, and so constructed that the sections can be readily taken apart when not in use, as will be fully understood from the following description, when taken in connection with the annexed drawings, in which- Figure 1 is a perspective view showing my improved cook stove ventilator erected in proper position upon a stove. Fig. 2is arear elevation of the ventilator on the upper part of a stove. Fig. 3 is a plan view, enlarged, of the cap-plate of the ventilator, and a horizontal section taken in the plane indicated by dotted line X X on Fig. 4, showing the damper. Fig. 4 is an enlarged vertical section through the upper part of the ventilator from front to rear. Fig. 5 is a vertical section through the lower partof the ventilator, showing the construction of one of the devices which clamp it to the flange of the top stove-plate. Fig. 6 is an enlarged vertical section through the upper part of the ventilator, showing the manner of securing the several sections thereof together. Fig. 7 is a vertical section through the upper part of the ventilator, taken 'in the plane indicated by dotted line 3 3/ on Fig. 8. Fig. Sis a section taken in the horizontal plane indicated by dotted line X X on Fig. 7. Fig. 9 is a perspective view in detail showing the manner of connecting the parts at each corner of the upper sections. Fig. 10 is a perspec tive view, in detail and section, showing the manner of connecting the parts forming the intermediate or middle section. Fig. 11 is a perspective view of one of the end frames of the top section of the ventilator.

For the purpose of aiding in giving a full and clear description of my improved ventilator O, I shall divide it into a lower section, Z), a middle section or drier, b, and a top or cap section, b clearly shown by Fig. 1. The lower section, b, is composed of check pieces or standards, each comprising a rigid frame, 0, preferably of the form shown by Fig. 1, having sheetmeta-l panels 0 riveted to the inner sides of its flanges. To the back flanges of the standards 0, I rigidly secure two sheet-metal plates, 1) D, which are lapped at their meeting edges and adjustably'connected together at these edges by means of studs f, the necks of which pass through oblong slots f. The plates 1) D constitute the back of the lower section, b, and their upper and lower edges are sloping, as shown in Fig. 2, for a purpose hereinafter explained.

Apertures are ma zontal ends of the frame 0, and through each aperture is passed from without inward the shank of a hooked clamp, e, the hook of which engages with the flange of the top plate, a, of a stove, A, as shown in Fig. 5.

The clamps are tightened and the ventilator rigidly secured to the stove by means of screws 6, which are tapped through lugs 6*, formed on the lower ends of the frame 0, which screws forcibly-bear upon the shanks of the said hooked clamps. The middle section, b, is rectangular in shape, and is composed of two horizontal rectangular frames, at d, the bars of which are rectangular in cross-section,as shown in Fig. 6.

The frames are provided with panels (i which are held in their places by means of lugs (2 (Shown clearly in Figs. '7, 8, and 10.) The said frames are secured to corner angleiron posts 9, having shoulders g", and angular slotted ends g through the slots 9, in which are passed bolts, as shown in Fig. 7. There is no panel in the front side of the middle section, b, but in lieu thereof I apply a hinged door, E, and for the bottom of this middle section I employ a light removable grate or reticulated plate, G, scored out, as shown in Fig. 8. for the passage of that part B of the stovepipe which is secured directly upon the stove.

The bottom frame, (I, of the middle section, I), has slots 21. through its end bars, as shown in Figs. 7 and 8, through which pass bolts that unite the standards 12 to the middle section,

de through the lower hori IOC b, and allow them to be adjusted laterally to adapt the ventilator to stoves varying in width; but where stoves vary considerably in width I provide for springing the lower ends of the said standards outward or inward, so that the hooked clamps 6 may be engaged with the flanges of a stoveplate, as above described- It will be seen that by sloping the upper and lower ends of the back plates, D D, and lap ping the vertical edges thereof, as shown in Fig. 2, the lower ends of the standards can be adjusted, as described,-to stoves of different widths Without leaving an opening through the back of the ventilator, which would impair the draft thereof.

The top section, b, of the ventilator is preferably pyramidal in shape, the front and end sides inclining inward and the back vertical. This upper section, If, is composed of rigid angular frames m, having angular pins or flanges n at their angles, which are notched at 10, so that when the edges of the said frames at are properly adjusted together the notches 19 form slots through which bolts are passed that pass through the upper frame, (1, and rigidly secure the top-section frames to the middle sec-' tion.

The flanges a at the upper edges of the frames m and bolts and nuts are used for securing a horizontal cap-plate, 1", upon said frames, as shown in Figs. 3, 6, and 7 of the annexed drawings. This top plate, 7', has an aperture centrally through it, through which passes the upper end of the lower section, B, of the stove-pipe, as shown in Fig. 4, and surrounding this aperture is a collar, 25, adapted to receive upon it the lower downwardly-flaring end of the upper section, B, of the stovepipe.

Between the collar t and the said aperture the top plate has holes through it, and an annular damper or register, S, provided with a handle,=is applied in the space between the collar and upper projecting end of the stove pipe section B.

During the process of cooking if the register S be opened practically all of the vapors rising from the stove will be drawn into the hood through the middle and upper sections thereof, and thence out through the register intothe flue or pipe B, where the vapors mix with the products of combustion from the firebox of the stove and escape into the chimney.

In starting a fire, or whenever it is desired,

the register may be closed or partly closed.

By simply loosening the corner bolts of the posts 9 and the bolts which secure the lower frame of the middle section to the standards b, the several detachable parts can be knocked down and. packed in a very small space for storage or transportation.

=Having fully described my invention, I claim-- 1. The within-described ventilator for cookstoves, comprising two cheeks and a superimposed housing open at the'bottom, and provided with a register at the top surrounding the outlet-flue, in combination with a back composed of the plates D D, slotted at f, and

provided with connecting-pins f, substantially as and for the purposes described.

2. The combination, in a ventilating-hood for stoves, of the cheek-pieces, the two adjustable back plates, the superimposed housing provided with a register and a front door, and

a main outlet-flue extending from the stove through the top of the said housing, substantially as described.

3. In a stove ventilator, the combination, with the upper and lower sections, of the rectangular middle section composed of paneled frames, the corner-posts 9, provided with slots at their upper and lower ends, the screw-fastenings, and the lugs d", adapted to receive the panels d", all constructed and adapted to operate substantially as described.

4. In a stove ventilator or hood, the combination of the lower section, b, composed of paneled cheek-pieces, the back thereof composed of annular lapped plates D D, slotted and connected together by studs, the superimposed intermediate section, I), having a front door, and composed of angular frames and corner-posts, and a pyramidal section, If, also composed of angular paneled frames, and provided with a register adapted to receive through it the main flue, and a collar adapted to receive the upper part of the stove-pipe, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN F. LINSGOTT.
